Tezos is a decentralized, open-source blockchain network that can execute peer-to-peer transactions and serve as a platform for deploying smart contracts. The native cryptocurrency for the Tezos blockchain is the tez or tezzie, which has the symbol XTZ. As of January 2021, there are over 400 block validating nodes (bakers) on the Tezos network. The vast majority of transactions currently happening on Tezos today though are mostly to maintain consensus and are not for more substantive operations, such as executing smart contracts, even though the network has the capacity to handle many more transactions.
The Tezos network achieves consensus using a liquid proof-of-stake model. Tezos features an on-chain governance model that allows the protocol to amend itself when upgrade proposals receive a favorable vote from the community. This feature allows Tezos to avoid hard forks that other blockchains have to contend with.
Tezos was first proposed in a whitepaper published in 2014. Its testnet was launched in June 2018, and its mainnet went live in September 2018.
Tezos received media attention for its large initial coin offering in July 2017, which raised $232 million, and subsequent public disagreements between its founders and the non-profit Tezos Foundation that was set up to manage the raised funds. Those disagreements led to delays in the deployment of Tezos, which caused investors in the project to bring lawsuits against its founders and the Tezos foundation.
